What is the central theme to this everlasting spoof?

If my knowledge serves me correctly,
Phish makes references to TIME and increments of time more than any other subject matter.

Here are some off the top of my head...Vultures is a great example but there are so many...

"Timing is everything, that much I know.
Sometimes I'm fast(er) and sometimes I'm slow
Some days vacation but some days I'm told
I've come to to the end of the line
But when I can't be what's expected of me
I look at the clock and say this can't be
Watching it pass without reason or rhyme
I feel I'm suspended in time"

Time Turns Elastic, In and out of focus
Well they say TIME loves a hero!

Stealing Time from the Faulty Plan

Time for the meatstick, take out the meat stick time

Time time time for the last rewind

If time were only part of the equasion

Come waste your time with me

The Time labratory from NYE 1995

The Harpua where they freeze time and we're stuck in 1996 " The Horrible sound of Hell"

The Meatstick NYE clock from Big Cypress

Time by Pink Floyd

Good Times Bad Times

Party Time

That time then and once again, im bouncing round the room
I was taught a month ago To bide my time and take it slow
This time will be different , until i do it again
There ain't no time to stash the Gumbo

Take me to another place, she said, Take me to another timeWhen all the time spent leading I've been following instead
Waiting for the time when I can say this has all been wonderful but now im on my way...
Time keeps on slippin slippin slippin into the future!!!
